- 53. Conclusions There is no one-size-fits-all solution in Cloud migration
- 54. Conclusions Netflix wasn't built in a day… Leverage Cloud’s potential is not so easy “Given the obvious benefits of the cloud, why did it take us a full seven years to complete the migration? The truth is, moving to the cloud was a lot of hard work, and we had to make a number of difficult choices along the way.” Yury Izrailevsky - Vice President, Cloud and Platform Engineering @Netflix
